Efficacy and Safety of Polaprezinc (Zinc Compound) on Zinc Deficiency: A Systematic Review and Dose-Response Meta-Analysis of Randomized Clinical Trials Using Individual Patient Data
Nutrients (2020) · Meta analysis
The dose-combined overall polaprezinc increased the change from baseline by a mean of 9.08 µg/dL (95% confidence interval: 5.46, 12.70; heterogeneity: I2 = 0.61%) compared to the placebo.
The 600 mg point is an 8-week placebo-controlled trial in 55 overweight adults with impaired fasting glucose, where the extract improved fasting glucose, HOMA and the lipid pattern against placebo (PMID 23440660). The 1,280 mg point is a 12-week placebo-controlled trial in 75 adults with mild to moderate high cholesterol, where total cholesterol fell 4.2% against a 1.9% rise on placebo, with no difference in LDL, HDL or triglycerides (PMID 18424099). The two trials used different extracts and populations, and none compared doses, so the curve is flat and no optimal dose is set. No cited trial tested more than 1,280 mg for cholesterol.
Doses are polaprezinc a day, added to standard triple therapy. In a 303-patient RCT, 75 mg or 150 mg twice daily (150 or 300 mg a day) raised eradication to 77.0% and 75.9% versus 58.6% with triple therapy alone, with no difference between the two doses and more adverse events at 300 mg (5.1% versus 2.8%) (PMID 28407007). A smaller RCT of 300 mg a day with a different triple regimen found no significant gain (80.4% versus 78.2%) (PMID 15786539). A meta-analysis of 3 trials (396 patients) found higher eradication with polaprezinc (OR 2.01) but did not compare doses (PMID 36235778). The curve is flat above 150 mg because the higher dose added nothing.
